I didn’t watch that game till late last night on replay. Saw that Denver was in the hot sun most of the game and I recall heat being an issue on the visitor’s sidelines at that stadium, that it gets up to or over 100F when the regular temp is in the 80s. I wonder if Broncos weren’t prepared for that and just wilted in that Miami heat. Peyton & training staff should have prepared team for it so it’s on them. Miami has the climate advantage like Buffalo has in December/January.
It was actually mentioned during the broadcast that Denver spent a few extra days in Miami before the game trying to get acclimated. Whether that was successful or not might not be knowable, but there was an attempt.
